Some of our finds were published this year, and some are a few years old. Most are due to duplication; one is due to “use of a dataset without ethical approval.” Chan — now the Associate Master and Chief of Students at the University of Macau — is the first author on all but one of the papers.

We’ll start with the most recent errata. Three of Chan’s articles in the Journal of Clinical Nursing have errata notes published online in July of this year, all noting that the authors used elements of some of Chan’s other articles.Here’s the erratum note for “ExploringriskfactorsfordepressionamongoldermenresidinginMacau:”

The journal’s editor-in-chief, Debra Jackson, confirmed the dates and said that “a commercial company” brought the matter to their attention. After the journal asked a statistician to weigh in, they stated that a “substantial re-write would be required to correct the article,” and a retraction would be “the most suitable course of action.”

Although she said the authors initially sought to correct, not retract, the study, they eventually agreed with the decision.
